Gary K. Smith said this quote
“ Sorrow is specific. Sorrow is vibrational. Sorrow is the state of depressed dimensional fields in and around the heart region. So actually, what is being said here is that there comes a time when an individual cannot love enough to transmute certain experience. Certain experiences are so challenging that the individual’s heart region depresses. If one can transmute shocks to the heart, and regain or hold heart balance, then one understands the “mathematics of sorrow” at that dimensional spectrum. ”
